They’re like that in this apartment we’re renting and I keep seeing them elsewhere. I don’t get it.
when any electricity leaks out (for example through your body) it switches off. the eu also has the same system, but its one switch for your entire house. the us also has this but only in bathrooms.
These aren’t automatic switches, but other people explained the reasoning.
oh, according to electroboom they were gfci.
They’re connected to an RCD, as modern UK wiring has all sockets connected via an overall RCD in the fusebox, but the switches on the socket are just basic on/off switches.
GFCI circuits are required by code around sinks and the like. Bathrooms, kitchens, utility wet rooms, etc.
You can relatively easily install them anywhere you want though.
